SPECIFICATION forming part of Letters Patent No. 384,411,:1ated June 12,1888.

Application filed November 4, 1887. Serial No. 254,294. (No model.)

To all whom it may concern:

Be it known that I, TELESPHORE BABIN, a citizen of the United States,and a resident of Houma, in the parish of Terre Bonne and State ofLouisiana, have invented certain new and useful Improvements in CoffeeStrainers or Filters; and I do hereby declare that the followingisafull, clear, and exact description of the invention, which willenable others skilled in to the art to which it appertains to make anduse the same, reference being had to the accompanying drawings, whichform a part ofthis specification, and in which Figure 1 is a perspectiveview of my improved filter or strainer for coffee. Fig. 2 is a verticalsectional view and Figs. 3 and 4 are detail views of the dripper-chamberand dripper-tube, respectively.

Similar numerals of reference indicate corresponding parts throughoutthe several views.

My invention has relation to improvements in filters or strainers forcoffee and other like substances; and it consistsiu the improvedconstruction and combination of parts of the same, as hereinafter morefully described and set forth.

Referring to the several parts by their designating-numerals, 1indicates the water-reservoir or boiler, 2 the steanrescape pipe, 3 thewater pipe or tube, and 4 the handle, of my device.

Communicating with the water pipe or tube 3 is a transverseconnecting-pipe, 5, which in turn communicates with a downwardly -eX- 5tending discharge chamber, 6, said chamber being provided withscrewthreaded lower end adapted to receive the screw-threaded end of afunnel-shaped dripper-chamber, 7. The dis charge-chamber 6 is screwedwith its upper 0 screw-thread extension or gudgeon, 16, into ascrewthreaded socket, 17, secured in any suitable manner to thetransverse connectingpipe 5. A perforated cone-shaped drippertube, 8,passes through the dripper-chamber,

5 the lower end or apex thereof extending below the lower end of saiddripper-chamber, so as to leave the perforations at this point perfectlyfree and unobstructed.

Fitting in the interiorly-screw-threaded upper end of the steam escapepipe 2 is a screwthreaded cap, 9, having central perforation, 10, andalso provided with an annular flange or collar, 11, bearing against theupper end of said pipe or tube.

12 is a removable valve or plug having shank 5 or stem 13 passingthrough the central perforation of the cap 9, said valve or plug beingsuitably secured to the steam-escape pipe by a light chain, cord, orother suit-able means.

It will be seen that the steamescape pipe or tube does not communicateat its upper end with the transverse connecting pipe 5, nor does thelower end thereof extend down into the boiler or watcr'reservoir, simplyterminating at the upper surface thereof, for the purpose of admittingsteam from the boiler, and permitting the same to escape when desired.The water pipe or tube 3, however, as stated, communicates with thetransverse connectingpipe 5, which in turn communicates with thedownwardly-extending chamber 6. The lower end of said water-pipe 3preferably extends down into the water-reservoir within onehalf an inchof the bottom thereof.

This being the construction of my improved filter or' strainer forcoffee and other substances, the operation is as follows: VVater isfirst introduced into the reservoir or boiler by removing the safetyvalve or plug 12, and also the screw-threaded cap 9, and utilizing thedripper chamber 7 as a funnel, which may readily be done by simplyunscrewing the same from the downwardly-extending chamber 6 and removingthe dripper tube therefrom. Care should be taken to introduce sufficient8 water to at least submerge the end of the water-pipe. The groundcoffee or other substance to be defecated or filtered is now placedwithin the dripper chamber, said dripper chamber, with its (lripper-tubeinserted there- 0 in, being replaced in proper position upon the end ofthe downwardly-exteuding chamber 6. After properly adjusting the cap andthe re movable valve or plug in the end of the steamescape pipe, thewater contained in the reser- 5 voir is subjected to heat, and as thesteam arises from the boiling water it will fill the space above thesurface of the water, and also enter the steam-escape pipe. Inasmuch,however, as there is no outlet for the steam, the remov- 10o able valvebeing in proper position in the end of the steam-pipe, the expansivepower of the steam will exert a pressure upon the water, forcing thesame up through the water-pipe into the transverse connecting-pipe,whereit will pass down to the dripper-chamber, and finally be discharged fromthe end of the dripper-tube. A cotfeepot or other like vessel may beplaced upon the reservoir or boiler to receive the essence or deeoctionas it slowly passes through the dripper-tube.

In operation care should always be taken to keep at least halfan inch ofwater in the boiler, so as to prevent any accident or wear which mightotherwise arise should the water be allowed to fall below this mark.

It will be seen that when the water eontai ned in the reservoir fallsbelow theend of the water pipe or tube it will be prevented fromentering or being forced into said pipe, and this will also be the casewhen the steam valve or plug is removed,which of course permits thesteam to escape, thereby removing all pressure upon the surface of thewater. The removable valve or plug is also intended to act automaticallyin case of an overcharge of steam, the pressure of the steam upon thevalve in such case being sufficient to force the valve out of positionwithin the perforation of the screw-threaded cap 9.

From the foregoing description, taken in connection with theaccompanying drawings, the construction, operation, and advantages of myimproved filter or strainer will be readily understood.

In practice I prefer to use my invention on oil-lamps; but it is obviousthat it can be employed in connection with a stove or any other suitableheating apparatus. l

The device is simple and exceedingly effectl ive in its work, thearrangement of the drippertube within the dripper-chamber being suchthat the substance to be defeeated will undergo a very thorough andeffective filtration, the fine perforations in the Gripper-tuberendering the process of filtering sufliciently slow to insure theextraction of the virtues of the berry.

Having thus described my invention, I claim and desire to secure byLetters Patent of the United States 1. In a strainer or filter forcoffee, the combination of the steam-escape pipe having aninteriorly-threaded upper end, the removable screw-threaded cap having acentral aperture and provided with an annular flange or collar, and thevalve or plug suitably secured to the steam-escape pipe and adapted tobe inserted in the central aperture of said removable cap.

2. The combination of the waterreservoir or boiler, the steamescape pipehaving interiorly threaded upper end, the removable screw-threaded caphaving central aperture and provided with an annular flange or collar,the valve or plug suitably secured to thesteainescape pipe and adaptedto be inserted in the central aperture of said removable cap, thewater-pipe, the transverse connecting-pipe, the downwardly extendingdischarge chamber having the lower screw-threaded end, the funnel-shapedinteriorly-threaded dripper-chaniber, and the coneshaped perforateddrippertube.

In testimony that I claim the foregoing as my own I have hereuntoaffixed my signature in presence of two witnesses.
